One of zynthian's primary instrument weapons. It handles sf2 sample files which can contain a range of samples. Fluidsynth itself doesn't have a graphical frontend but it's designed specifically to allow other software to control it remotely which has lead to a range of control surfaces, of which the early use in zynthian demonstrates the flexibility of this approach.

Pianos, organs, strings, harpsichords, marimbas, guitars, bass

So you have access to the many sf2 files that are out there providing ranges of samples to impersonate almost any instrument one could model from a western 12 note scale!

Most people will simply load up the appropriate files and use them exactly as is and the zynthian parameters

1.4 Other uses

But it doesn't have to be a full range of sounds ...

For instance I have 8 church bells in a sf2 file allocated to the keys of the F major scale which plays the appropriate sound when pressed.

There are also some Mellotron & it's antecedents sf2 files out there ( I bought mine) that allow the features like the foxtrot and a lead saxaphone to be played in single finger fashion....
